Today Pierre-Loup announced that the SteamOS update 133 has been pushed to the Alchemist Beta.

Besides the normal security fixes, this release features a newer Linux kernel (no specifics) that boasts more network drivers and better Intel graphics performance. On top of that this release also features the Nvidia 340.32 drivers which fixes some of the white screen bugs when switching between modes.

Personally I'm happy to see a newer kernel be released, but I'm still waiting for Valve to introduce Steam Video/Music. What do you guys think?

as soon as this stuff is ready im gonna build a small, low energy, totally passive unit that i will install at the back of my tv to serve as home server, htpc and inhouse streaming gaming unit. currently intel bailtrail would be what id look for with something like an J1900 celeron processor and a built in DC power connector (something like this).
the delay of steamOS doesnt upset me tho.. 14nm process is coming and will allow for more processing power in a passivly cooled unit.
